Safe mobile data storage method based on fingerprint U disk and virtual machine

Abstract

The invention discloses a safe mobile data storage method based on a fingerprint U disk and a virtual machine. The method comprises the steps of: starting a computer from the U disk; loading a U disk guide program in an internal memory for guiding, prompting for inputting fingerprints or passwords; inputting the fingerprints or passwords, after the fingerprints or passwords pass verification, entering the next step, otherwise, prompting failure; guiding a bottom operation system mounted on the U disk by the guide program, and then automatically operating a virtual machine manager; entering a front end interface of the virtual machine manager, selecting a virtual machine for operation, operating data, storing the data or mounting application software on a virtualized windows operation system, and supporting full disk encryption of the U disk by the virtual machine. The method has the advantages of reducing possibility of U disk poisoning, preventing loss of important information, beingconvenient for use, avoiding data loss caused by the loss of the U disk, supporting backup and recovering the data under the condition that the U disk is lost.

Description

technical field [0001] The invention relates to the technical field of data storage, in particular to a secure data storage method based on a fingerprint U disk and a virtual machine. Background technique [0002] In today's environment of rapid information expansion, mobile storage tools such as U disks have the advantages of convenient use, fast transmission, and high security performance. In today's increasingly frequent data exchange, no matter personal, professional or enterprise Users tend to use USB flash drives to save important data. This usage mode itself puts forward new requirements for product performance, that is, security is especially important. [0003] Many people choose to store important or private files in a USB flash drive instead of storing them in the hard disk of the computer for a long time. Therefore, mobile storage tools led by the USB flash drive have become the top priority for data security protection. [0004] But information security is alwa...

AI Technical Summary

Problems solved by technology

[0010] 1. The software is easily monitored by Trojan horses on the PC. After all, the decrypted data is exposed in the memory, and the PC where it is located may have some viruses that read the memory data.

[0011] 2. The software needs to be saved in the USB flash drive. When using it, copy the software to the PC, which leads to the compatibility problem of the software on the operating system. It is possible that the operating system does not support the software, such as copying the Windows software to the Apple can't run on the machine

[0012] 3. The important data of the U disk cannot be backed up. If the file system format of the U disk is damaged, important data will be lost

[0013] Therefore, the products on the market do not actually reach a high degree of safety and reliability
